Two years ago, the Ethiopian singer Ejigayehu "Gigi" Shibabaw recorded a best-selling Africa-funk-jazz crossover set, simply titled Gigi, in which she was joined by a celebrity cast that included the likes of Wayne Shorter, Herbie Hancock and David Gilmore.

Now she's back with another excellent, more African-influenced album, on which she sings lead vocals, has written all the songs that aren't traditional, and acts both as co-producer and arranger. And yet, mysteriously, this is not being promoted as a Gigi album. It's titled Zion Roots, which makes it sound like a mediocre reggae set, and it's credited to Abyssinia Infinite "featuring Gigi".

The result is far more interesting than the packaging would suggest. The musicians are mostly Ethiopian, and are joined by the album's co-producer Bill Laswell, playing keyboards and acoustic guitar.

Gigi's clear, soulful vocals are backed by a subtle blend of insistent percussion, traditional Ethiopian flute and harp, along with saxophone and chugging accordion, while Laswell's wash of keyboard effects is for the most part a discreet addition. From the gentle Gela to the more jazz and gospel-influenced Lebaye (both of which she wrote) this is Gigi's album and she deserves the credit.
